BACKGROUND The sex composition of existing children has been shown to influence childbearing decision-making and behaviors of women and couples. One aspect of this influence is the preference for sons. In India, where son preference is deeply entrenched, research has normally focused on rural areas using cross-sectional data. However, urban areas in India are rapidly changing, with profound imp...

A numerical study is presented of the residual strength of an aircraft fuselage in the presence of multiple site damage (MSD)/muItiple element damage. The analyses were carried out using a software package that was developed to facilitate automated analyses of full-scale fuselage panels with widespread fatigue damage, using a hierarchical approach and elastic-plastic finite element alternating ...

BACKGROUND In children with hypoplasia or aplasia of the radius (radial longitudinal deficiency) manual activity limitations may be caused by several factors; a short and bowed forearm, radial deviation of the wrist, a non-functional or absent thumb, limited range of motion in the fingers and impaired grip strength. The present study investigates the relation between these variables and activit...

OBJECTIVE The current study aimed to examine homocysteine in relation to different aspects of physical functioning. DESIGN, SETTING AND PARTICIPANTS Cross-sectional and longitudinal data (3-years follow-up) from the Longitudinal Aging Study Amsterdam (LASA) were used. The study was performed in persons aged ≥ 65 years (N= 1301 after imputation). MEASUREMENTS Different measures of physical f...

Skeletal muscle fibers hypertrophy in response to strength training, with type II fibers generally demonstrating the greatest plasticity in regards to cross-sectional area (CSA). However, assessing fiber type-specific CSA in humans requires invasive muscle biopsies. With advancements in the decomposition of surface electromyographic (sEMG) signals recorded using multichannel electrode arrays, t...

Trabecular plates play an important role in determining elastic moduli of trabecular bone. However, the relative contribution of trabecular plates and rods to strength behavior is still not clear. In this study, individual trabeculae segmentation (ITS) and nonlinear finite element (FE) analyses were used to evaluate the roles of trabecular types and orientations in the failure initiation and pr...

The great diffusion of masonry arch bridges, sometimes historical interest, requires the development simple but effective methodologies for a preliminary reliable evaluation their static and seismic capacity. In this paper, behaviour under longitudinal actions is analysed by using mechanism method. supposed to have no tension strength rigid–perfect plastic with finite in compression. subject pe...

Abstract The main aim of this investigation was to study the flexural strength and drift ratio simply supported rectangular RC hollow beams (with a longitudinal square hole) subjected gradually increased symmetrically applied one-point load. Each beam had 300 mm2 900 mm2-area square, position center hole 80 mm from top. cross-section beam, amount steel, stirrups kept constant. deflection these ...
